The compositions cause significantly less ulceration compared to the same formulation of cytotoxic compound without cyclodextrin compound when extravasated. The compositions may also cause less vascular irritation compared to the same formulation of cytotoxic compound without cyclodextrin when administered intravenously without extravasation. Compositions of matter comprising watersoluble cytotoxic agents, especially anticancer drugs and anti-ulceration effective or anti-irritation effective amounts of cyclodextrin compounds are also claimed. Methods for reducing the likelihood of ulceration and/or irritation when administering the compositions according to the invention are also disclosed and claimed.

Description: Improved Pharmaceutical Formulation Field of the Invention The present invention relates to improved pharmaceutical formulations. Background of the Invention. Many compounds that can be injected intravascularly into animal and human patients for a beneficial effect have the undesirable hazardous side effect of causing ulceration at the injection site as a result of extravasation. Extravasation is strictly defined as the forcing of fluid out of a blood or lymph vessel into the surrounding or perivascular tissue. More broadly defined, extravasation may be said to occur when an injection solution and blood or serum combined with an injection solution leaks out of a blood vessel during intravascular administration of the solution or subsequent thereto, at the site of injection or when the injection solution is accidentally injected into tissue surrounding a blood vessel. Such extravasation may occur as a result of accidentally failing to properly insert a needle for the intravascular administration of a solution into the lumen of a blood vessel. It may also occur by accidentally inserting a needle entirely through a blood vessel intended for intravascular administration. In addition, leakage of solution from a blood vessel may occur if a blood vessel is too small for the rate and volume of injection solution being injected into the blood vessel. Lastly, leakage of solution from a blood vessel may occur if the blood vessel has been damaged or eroded by prior injection or other trauma. Extravasation of certain intravasuclarly administered compounds may lead to formation of a deep, spreading and painful ulcer which may require surgical extirpation of the affected tissue. Skin grafting is frequently required to repair and reconstruct the resulting wound. Another complication of such intravascularly administered compounds is that they are irritants causing irritation of the lining of the blood vessel into which they are injected. This irritation may be accompanied by pain at the site of injection or along the length of the blood vessel. In addition the irritation may lead to reduced patency of the blood vessel and in some cases may induce the formation of blood clots in the affected blood vessel leading to a risk of gangrene or emboli. Not all injection solutions cause ulceration as a result of extravasation; however; many pharmaceutical compounds injected for particular chemotherapeutic effects in many therapeutic categories have this presently unavoidable side effect. Pharmaceutical compounds having this side effect are well known to those skilled in the art of administration of such compounds to patients and animal subjects. The side effects of such drugs are collected in a number of publication including the Physicians Desk Reference published yearly by Medical Economics Data, a division of Medical Economics Company Inc., Montvale New Jersey 07645 USA and the United States Pharmacopeia Drug Information published and supplemented by the Untied States Pharmacopeial Convention , Inc. 12601 Twinbrook Parkway, Rockville, Maryland 20852, USA. Similar volumes are published else where in various countries of the world. Among the pharmaceutical compounds that cause extravasation associated ulceration are cytotoxic compounds which are administered to patients and animal subjects for the purpose of manifesting a specific cytotoxic effect. Such cytotoxic compounds include many anticancer or antineoplastic compounds. These compounds may be synthetic chemical compounds, such as nitrogen mustard derivatives such as mechlorethamine, plant alkaloids such as vincristine and vinblastine, alkylating agents such as dacarbazine and streptozocin or microbially produced and purified or partially purified antibiotics. Cytotoxic antibiotics include those administered as anti-cancer agents, such as mitomycin, bleomycin, daunorubicin, doxorubicin, plicamycin and dactinomycin. In addition antifungal antibiotic agents such as amphoteracin B can cause ulceration associated with extravasation. Furthermore, therapeutic compounds which are not administered to achieve a specific cytotoxic effect may also result in extravasation associated ulceration. For example certain sedative compounds when injected intra- vascularly (IV) can cause severe ulceration if extravasation occurs. Such sedative compounds include but are not limited to benzodiazapine compounds including diazepam. Thus, there is a long felt need for safer formulations of injectable pharmaceutical compounds to reduce or eliminate ulceration resulting from extravasation. Pharmaceutical preparations containing cyclodextrin are known. Human sex hormones including, estradiol-, progesterone- and testosterone - hydrophilic cyclodextrin derivatives, especially hydroxypropyl cyclodextrin suitable for oral mucosal or rectal mucosal administration are disclosed in U.S. Patent 4,596,795. These preparations are disclosed as increasing the circulating half life of the hormone through elimination of absorbance via the gastrointestinal tract and consequent removal by hepatic clearance. There is no disclosure of complexes that reduce local ulceration or irritation at an injection site. U.S. Patent 4,727,064 disclosed pharmaceutical preparations consisting generally of a drug with a substantially low water solubility and an amorphous water soluble cyclodextrin-based mixture having improved dissolution properties and absorption by the body. The solutions of amorphous water soluble cyclodextrin are disclosed as non- irritating topically, and having low toxicity, both systemic and local, when applied parenterally. None of the amorphous cyclodextrin-drug mixtures disclose in the specification or claims discloses a complex including a drug that causes ulceration when extravasated and there is no disclosure concerning reduction of ulceration as a result of administering the drug in a complex with an amorphous cyclodextrin complex. A variety of improvements in the characteristics of pharmaceutical complexes including various cyclodextrins and cyclodextrin derivatives are disclosed in the following United States patents, but none of them disclose the reduction in extravasation-associated ulceration, or irritation through the formation of complexes of cyclodextrin and pharmaceutical compounds : Noda et al., 4,024,223 methyl salicylate; Szejtli et al 4,228,160 indomethacin; Hyashi et al., 4,232,009 ω-halo-PGI 2 analogs; Matsumoto et al. , 4,351,846 3-hydroxy and 3-oxo prostaglandin analogs; Yamahira et al., 4,353,793, bencyclane fumarate; Lipari, 4,383,992 steroids-corticosteroids, androgens anabolic steroids, estrogens, progestagens; Nicolau, 4,407,795 P-hexadecylaminobenzoic acid sodium salt; Turtle, 4,424,209 3,4- diisobutyryloxy-N-{3-(4-isobuttyryloxyphenyl)-l-methyl-n-propyl]-jS-phenethylamine; Turtle, 4,425,336, 3,4-dihydroxy-N-[3-(4-hydroxyphenyl)-l-methyl-n-propyl]-/3- phenethylamine; Wagu et al., 4,438,106 fatty acids EPA and DHA; Masuda et al., 4,474,881 2-(2-fluoro-4-biphenyl)propionic acid or salt; Shinoda et al. , 4,478,995 acid addition salt of (2'-benzyloxycarbonyl)phenyl trans-4-guanidinomehtylcyclo- hexanecaboxylate; Hyashi et al., 4,479,944 Prostaglandin I 2 analog; Hayashi et al. , 4,479,966, 6,9-methano-prostaglandin I 2 analogs; Harada et al., 4,497,803 lankacidin- group antibiotic; Masuda 4,499,085 prostoglandin analog; Szejtli et al., 4,524,068 piperonyl butoxide; Jones, 4,555,504 cardiac glycoside; Uekama et al., 4,565,807 pirprofen; Ueda et al., 4,575,548 2-nitroxymethyl-6-chloropyridine; Ohwaki et al., 4,598,070 tripamide anti-hypertensive; Chiesi et al., 4,603,123 piroxicam (feldene); Hasegawa et al., 4,608,366 monobenzoxamine; Hiari et al., 4,659,696 polypeptide; Szejtili et al. , 4,623, 641 Prostoglandin I 2 methyl ester; Ninger et al., 4,663,316. unsaturated phosphorous containing antibiotics including phosphotrienin; Fukazawa et al. , 4,675,395 hinokitol; Shimizu et al., 4,728,509 3-amino-7-isopropyl-5-oxo~5H-[l]- benzopyrano[2,3-b]pyridine-3-carboxcylic acid; Shibani et al. , 4,728,510 milk component Karl et al 4 , 751 , 095 aspartame . Among the above-mentioned patents, several indicate that complexes of cyclodextrin with drug substances improve side effects of the drug substance. Szejtli et al., 4,228,160 disclosed that the frequency and severity of gastric and duodenal erosion and ulceration in rats caused by indomethecin is improved in an oral formulation of a complex of /3-cyclodextrin: indomethacin in a 2:1 ratio, but is not improved and in fact worsens in the same oral formulation of a complex of /3-cyclodextrin: indomethacin in a 1:1 ratio. Shimazu et al. , 4,352,793 discloses that a formulation wherein bencyclane fumarate an anti-convulsive compound and /3-cyclodextrin or γ-cyclodextrin yield a complex in which the bencyclane fumarate is an inclusion compound. These complexes, when formulated as a liquid suitable for oral administration were claimed to be less irritating in an isotonic buffered pH 7 solution when administered as drops to the eyes of rabbits, as compared to bencyclane fumarate drops at the same drug concentration. Shimazu et al., also discloses that similar complexes dissolved in rabbit blood in vitro yielded reduced hemolysis as compared to equal concentrations of bencyclane fumarate alone mixed with rabbit blood. There was no indication that this compound is cytotoxic or causes ulceration or irritation of the surrounding tissue when extravasated during or after injection. Masuda et al., 4,478,811 disclose ophthalmic formulations of β- or γ-cyclodextrin complexes of the nonsteroidal anti-inflammatory compound fluoro-bi- phenylacetic acid which are less irritating and painful than the same formulations of fluoro-bi-phenyl acetic acid alone. There was no indication that this compound is cytotoxic or causes ulceration of the surrounding tissue when extravasated during for after injection. Shinoda et al., 4,478,995 disclose complexes of a-, β- and y- cyclodextrin and acid addition salts of (2'-benzyloxycarbonyl)phenyl trans-4-guanidinomehty ley clo- hexanecaboxy late, and enzyme inhibitor having anti- gastric and duodenal ulcer activity. The complexes were administered orally and were more active in preventing ulceration than oral administration of acid addition salts of (2'-benzyloxycarbonyl)phenyl trans-4- guanidinomehty ley clo-hexanecaboxy late alone in solution. No preparation suitable for intravenous injection were disclosed and there was no indication that this compound is cytotoxic or causes ulceration of the surrounding tissue when extravasated during for after injection. Uekama et al. , 4,565,807 discloses complexes of -, β- and γ- cyclodextrin , pirprofen and a pharmaceutically acceptable base. Piprofen is an analgesic and anti-inflarnmatory compound which is bitter and can cause irritation to the gastrointestinal tract. The complexes disclosed in the patent have improved less bitter taste and are less gastrointestinal irritating than the un-complexed compound piprofen. No preparation suitable for intravenous injection were disclosed and there was no indication that this compound is cytotoxic or causes ulceration of the surrounding tissue when extravasated during for after injection. Bekers, O., et al.," Stabilization of mitomycins on complexation with cyclodextrins in aqueous acidic media" International Journal of Pharmaceutics, 53 (1989) 239-248 describes the investigation of stabilization of mytomycin-C and several related mitomycins by formation of a complex with cyclodextrin. The authors indicte that at the pH ranges studied - and β- cyclodextrin as well as heptakis-(2,6,-di-O-methyl)-/3- cyclodextrin and (dimethyl-/3- cyclodextrin have no influence on stabilization of mitomycin-C pH degradation, γ-cyclodextrin is reported as having measurable stabilizing effect on mitomycin in acidic media at pH above 1. There is no suggestion that stabilization of mitomycin-C from acidic degradation in aqueous media by complexation with γ- cyclodextrin is or can be related to amelioration of ulceration or irritation caused by mitomycin when administered to a patient. Bodor US patent 5,024,998 and Bodor US patent 4,983,586 disclose a series of compositions comprising complexes of :Beta hydroxypropylcyclodextrin (HPCD)- complexed to a difficult to solubilize drag, or HPCD complexed to a drag- which has first been complexed to a sepcific class of drag carriers characterized as redox drug carriers.. The complex of drag and redox carrier is itself difficult to solubilize and is highly lipophilic due to the presence of pyridine derivatives as part of the redox carrier complex. Bodor '998 and 586 further claim that a solution of 20 to 50% hydroxypropylcyclodextrin-and lipophilic drug-redox carrier complex or 20 to 50% hydroxypropylcyclodextrin-and lipophilic and or water labile drag is useful in a method of "decreasing the incidence of precipitation of a lipophilic and/or water labile drag occuring at or near the injection site and/or in the lungs or other organs following parenteral administration. Neither of the Bodor references mentions the problem of irritation associated with the administration of these water soluble compounds or ulceration assciated with their extravasation. Furthermore, neither of the Bodor references teaches or suggests that water soluble cytotoxic or antineoplastic drugs or the water-soluble salts of such drags when administered with cyclodextrin compounds can significantly decrease ulceration or irritation associated with administration or extravasation of such drugs. Significantly the Bodor references attribute the preciptiation and organ deposition problems associated with parenteral administration of lipophillic drugs to the effects of organic solvents used to solubilized the drag in the parenteral vehicle. The Bodor references additionally state that drags which are particularly useful in the parenteral composition and methods disclosed therein are those which are relatively insoluble in water but whose water solubility can be substantially improved by formulation with 20 to 50% of the selected cyclodextrin, e.g. HPCD, in water. Thus it is quite clear that the Bodor references are directed to prevention of the phenomenon of precipitation of insoluble drags and insoluble drag-carrier complexes. There is no disclosure concerning the prevention of ulceration or irritation or of amounts of the amorphous cyclodextrin useful for the prevention of these two side effects. Summary and Objects of the Invention The present invention provides a composition of matter comprising an anti- ulcerationeffective amount or an anti-irritation-effective amount of an amorphous complex of cyclodextrin and any compound which can cause extravasation-associated ulceration or irritation when injected. In general such compounds are cytotoxic compounds, but the compositions of matter according to the invention are not limited to cytotoxic compounds. For example certain sedative compounds when injected intravascualrly (IV) can cause severe ulceration if extravasation occurs. Such sedative compounds include but are not limited to diazepam compounds including diazepam. In addition, certain ionotrophic drags such as dopamine, may lead to ulceration if extravasated or to vascular irritation when injected. The present invention is useful in the prevention of extravasation-associated ulceration and initiation associated with injection of drugs that are insoluble in water as well as drugs that are soluble in water. It is particularly and unexpectedly effective in prevention of these side effects in the administration of water soluble cytotoxic agents. In particular, the present invention is a composition of matter that marks an improvement in the formulation of cytotoxic agents which are water soluble whereby the tendency of these agents to cause irritation or ulceration when extravasated on injection is substantially eliminated. By combining such water soluble cytotoxic agents with a cyclodextrin compound and preferably an amorphous cyclodextrin such as an alkyl- substituted or hydroxyalkyl-substituted c--, β-, or γ- cyclodextrin compound, irritation or ulceration when extravasated is substantially eliminated. Applicant has futher discovered that surprisingly the inclusion of an excipient such as mannitol, sorbitol or lactose further improves the performance of the composition in that the reduction in ulceration is even more pronounced than when the drag is used with the cyclodextrin compound alone. The phenomena of ulceration and irritation should be understood to be a different side effect than the phenomenon of precipitation which is addressed in the Bodor references. The distinction is clearest in the case of cytotoxic agents and particularly in the case of water soluble cytotoxic agents. In general the lipophilic drugs and drug-carrier complexes that Bodor discloses precipitate at the injection site or near to the side of injection , even when they are properly injected intravenously and not extravasated. Thus the fundamental teaching of the Bodor references relates to solubilization of insoluble drags so that they do not precipitate from the blood stream of a patient into the blood vessels near the site of injection or in more remote capillary beds of distant organs such as the lung. By contrast the phenomenon of extravasation occurs when the drag either leaks from a blood vessel into the perivascular tissue or is inadvertently injected into the perivascular tissue. When certain drags are extravasated they cause ulceration. It will therefor be appreciated that extravasation is particularly threatening when the drag is a water- soluble cytotoxic compound. Such water soluble drugs, instead of precipitating and leading to a localized ulceration, tend to disseminate into more distant tissues from the perivascular tissue immediate to the site of injection . This dissemination leads to extensive ulceration and not localized precipitation. Thus for example there are many reported cases in which localized extravasation of the water soluble agent doxorabicin leads to disseminated ulceration of the whole limb of the patient. Compositions of matter according to the invention comprising an amorphous complex of cyclodextrin and a cytotoxic compound may comprise a variety of different cytotoxic compounds used for a variety of therapeutic purposes. Such compositions according to the invention include an amorphous complex of cyclodextrin and an anti-cancer, anti- neoplastic, anti-fungal antibiotic, anti-bacterial antibiotic or chemical compound. Especially preferred in the compositions according to the invention are those in which the cytotoxic compound is one that is soluble in aqueous solution. Compounds that are soluble in aqueous solution include those in which the active drug is soluble. Also included are those drugs in which the acid complex of the active compound is soluble in water, such as doxorabicin hydrochloride. Additionally, a salt of an active drag formed to render the drug soluble is included in compounds that are soluble in aqueous solution.. Examples of the latter include vincristine sulfate and vinblastine sulfate (the sulfate salts of the active drag) and erythromycin lactobionate ( prepared from erythromycin base and lactobiono-δ-lactone). The cytotoxic compound may be a synthetic chemical compound such a nitrogen mustard derivative such as mechlorethamine. The cytotoxic compound may be a plant alkaloid such as vincristine and vinblastine or an alkylating agent such as dacarbazine and streptozocin. The compound may be microbially produced and subsequently purified or partially purified antibiotic. Cytotoxic antibiotics that may be part of the composition according to the invention include those administered as anti-cancer agents, such as the mitomycins including but not limited to mitomycin-c, the bleomycins including but not limited to mixtures predominating in bleomycin A2 and B, daunorubicin, doxorabicin, idarabicin plicamycin and dactinomycin. With respect to the compositions of matter comprising an amorphous complex of cyclodextrin and a cytoxic compound which is a chemotherapeutic anticancer agent, the anticancer agent may be a vessicant or an irritant. Composititons of matter in which the anti-cancer agent is a protein biological response modifier such as interleukin-2 or Tumor necrosis factor are not intended as the anti-cancer agents of the composition according to the invention; however compositions of matter which include such protein biologicaal response modifiers and an anti-neoplastic chemotherapeutic agent are intended as compositions according to the invention. Other cytotoxic antibiotics that may be part of the composition according to the invention include antifungal antibiotic agents such as amphoteracin B and certain anti-bacterial antibiotics, such as tetracycline and erythromycin that may lead to ulceration if extravasated or to vascular irritation when injected. Additionally, the compositions according to the invention include pharmaceutical compounds which are not administered to achieve a specific cytotoxic effect, but which may also result in extravasation-associated ulceration. Such compounds which may be part of the compositions according to the invention include, for example certain sedative compounds typified by benzodiazapine compounds including but not limited to diazepam. The compositions of matter according to the invention may also include, in addition to the amorphous complex of cyclodextrin and cytotoxic compound, carriers, bulking agents and other pharmaceutically acceptable excipients such as mannitol, sorbitol, lactose, dextrox and the like. Surprisingly, it has been found that certain chemotherapeutic compounds and such excipients, particularly mannitol, when formulated with cyclodextrin do not cause any significant extravasation when administered to mammalian subjects. The composition of matter according to the invention may be supplied as a dry powder or as a solution. If the composition of matter is to be injected into a subject it will be rendered sterile prior to injection. Accordingly, the composition of matter according to the invention may be supplied as a sterile cake, plug or powder or as a sterile lyophilized preparation in a sterile vial suitable for the addition of a sterile diluent, or as a sterile liquid solution in a sterile container.

Included in the phenomena defined herein as ulceration or ulcer are those phenomena usually associated with vesicants. See, Chapter 8 "Extravasation" in Cancer Chemotherapy, A Reference Guide, Linda Tenenbaum, W.B. Saunders Company, Harcourt Brace Jovanovich, Inc Philadelphia (1989); and Chapter 5 "Common Toxicities" in Cancer Chemotherapy Handbook, Robert T. Dorr and William L. Fritz, Elsevier, New York. The term ulceration or ulcer is not intended to include gastrointestinal, duodenal or intestinal irritation or ulceration associated with the oral administration of a number of oral analgesic and anti-inflammatory drags such as indomethacin By vesicant is meant a chemotherapeutic agent which is topically toxic. If inadvertantly delivered outside of a vein, a vesicant has the potential to cause pain, cellular damage including cellulitis, tissue destruction (necrosis) with formation of a sore or ulcer and sloughing of tissues that may be extensive and require skin grafting.

In a preferred embodiment the cyclodextrin is a substituted amorphous cyclodextrin, such as an alkyl or hydroxy alkyl substituted, including hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotrosyl derivatives of /3-cyclodextrin or 7-cyclodextrin and the cytotoxic agent is one that is soluble in aqueous solution. In general, the invention provides a composition of matter comprising an amorphous complex of cyclodextrin and any compound which can cause extravasation-associated ulceration or irritation when injected. While many such compounds are cytotoxic compounds, the compositions of matter according to the invention are not limited to cytotoxic compounds. For example certain sedative compounds when injected intravascualrly (iv) can cause severe ulceration if extravasation occurs. Such sedative compounds include but are not limited to diazepam compounds including diazepam. Compositions of matter comprising an amorphous complex of cyclodextrin and a cytotoxic compound according to the invention may comprise a variety of different cytotoxic compounds used for a variety of therapeutic purposes. Such compositions according to the invention include an amorphous complex of cyclodextrin and an anti- cancer, anti-neoplastic, anti-fungal antibiotic, anti-bacterial antibiotic or chemical compound. With respect to the compositions of matter comprising an amorphous complex of cyclodextrin and a cytotoxic compound which is a chemotherapeutic anticancer agent, the anticancer agent may be classified as a vesicant or an irritant. Examples of anti-cancer chemotherapeutic agents that are vesicants include but are not limited to Amsacrine, Dactinomycin, Daunorabicin, Doxorabicin, Idarabicin, Mechlorethamine, Mitomycin C, Vinblastine, Vincristine and Vindesine. Examples of anti-cancer chemotherapeutic agents which are irritants include but are not limited to Carmustine, Dacarbazine, Etoposide, Plicamycin, Etoposide, Streptozocin and Tenoposide. The effects of such agents on patients are found in the following Table B: Table B Acute Local tissue Drag Freαuencv of Phlebitis Effects (infiltration) Anthracyclines Daunorabicin Frequent Tissue slough Doxorabicin Frequent Large, spreading Dactinomycin Frequent ulcerations; deep tissues Idarubicin Frequent affected Alkaloids Vincristine Infrequent Vinblastine Frequent Cellulitis if small dose Tenoposide Frequent Slough if large dose Nϊtrosoureas Streptozotocin Infrequent Extravasation can cause Carmustine Infrequent extreme pain and necrosi Others Mitomycin Frequent Pain and eventual tissue sloughing Mithramycin Infrequent Chromomycin A 3 Frequent Sever tissue sloughing Decarbazine Frequent Pain, mild inflammation, slight necrosis In general , the composition of matter according to the invention will comprise a sufficient amount of the compound to exert its desired pharmacological effect when administered IV, whether it is for example sedation, anti-fungal activity, anti-neoplastic activity, and an amount of cyclodextrin compound sufficient to significantly reduce the extent of ulceration or irritation that would occur if a like amount of the compound were extravasated or administered IV without extravasation in the absence of the cyclodextrin compound. If the anticancer compound is a vesicant the composition of matter according to the invention will comprise a sufficient amount of the anticancer compound to exert its desired cytotoxic effect against targeted cancer cells and an anti-ulceration- effective amount of cyclodextrin, with or without an excipient. Likewise, if the anticancer compound is an irritant, the composition of matter according to the invention will comprise a sufficient amount of the anticancer compound to exert its desired cytotoxic effect against target cancer cells and anti-irritation-effective amount of cyclodextrin with or without an excipient. The anti-cancer chemotherapeutic compounds that may comprise the composition according to the invention will be any anticancer chemotherapeutic compound that causes irritation, as defined herein, or ulceration, as defined herein, upon extravasation. The compound may be a synthetic chemical compound such a nitrogen mustard derivative for example mechlorethamine. The antineoplastic compound may be a plant alkaloid. With respect to such plant alkaloids, taxol, a chemical compound derrived from the bark of the Pacific Yew tree, and pharmacologically active related compounds are contemplated. Also contemplated are water soluble compounds related to taxol such as taxotrere. While taxol is not water soluble, ulcerative activity caused by this anti¬ neoplastic compound may be significantly reduced by administration with hydroxypropyl-/3-cyclodextrin and it is believed that futher improvement in anti- ulcerativie effect will be obtained with amorphous γ-cyclodextrins Also contemplated in the compositions according to the invention are the vinca alkaloids. Such vinca alkaloids as vincristine and vinblastine and vindisine are particularly strong vesicants. Also among the anti-cancer chemotherapeutic compounds that may comprise the composition according to the invention are alkylating agents which are used as anti¬ cancer chemotherapeutics such as dacarbazine and streptozocin. The composition according to the invention may comprise a complex of cyclodextrin and a microbial produced antibiotic compound which is subsequently purified or partially purified. Cytotoxic antibiotics that may be part of the composition according to the invention include those administered as anti-cancer agents, such as the mitomycin including but not limited to mitomycin-c, the bleomycins including but not limited to mixtures predominating in bleomycin A2 and B, daunorabicin, doxorabicin, plicamycin and dactinomycin. All of the forgoing are soluble in aqueous solution. Anti-cancer agents which are protein biological response modifier such as interleukin-2 or Tumor Necrosis Factor are not intended as the anti-cancer agents of the compositions according to the invention since they do not cause ulceration or irritation as defined herein resulting from extravasation ; however compositions of matter which include such protein biological response modifiers and an anti-neoplastic chemotherapeutic agent which does cause extravasation associated irritation or ulceration are intended as compositions according to the invention. The composition according to the invention may comprise a complex of cyclodextrin and other cytotoxic anti-fungal antibiotic agents such as amphoteracin B. Additionally, the compositions according to the invention include pharmaceutical compounds which are not administered to achieve a specific cytotoxic effect, but which may also result in extravasation-associated ulceration. Such compounds which may be part of the compositions including cyclodextrin according to the invention include, for example certain sedative compounds typified by benzodiazapine compounds including but not limited to diazepam. In this instance, the composition according to the invention comprises an amount of the compound sufficient to exert the desired pharmacological effect when administered iv and an anti-ulceration or anti-irritation effective amount of the cyclodextrin compound. The compositions of matter according to the invention may also include, in addition to the complex of cyclodextrin and a chemotherapeutic compound , carriers, bulking agents and other pharmaceutically acceptable excipients such as mannitol, sorbitol, lactose, sucrose and the like. Surprisingly, it has been found that chemotherapeutic compounds and such excipients, particularly mannitol, when formulated with cyclodextrin do not cause any significant ulceration if extravasated when administered to mammalian subjects. The cyclodextrin of the compositions according to the invention may be -, β-, or γ- cyclodextrin. α-cyclodextrin contains six glucopyranose units; /3-cyclodextrin contains seven glucopyranose units; and 7-cyclodextrin contains eight glucopyranose units. The molecule is believed to form a truncated cone having a core opening of 4.7-5.3 A, 6.0-6.5 A and 7.5-8.3 A in -, β-, or γ- cyclodextrin respectively. The composition according to the invention may comprise a mixture of two or more of the -, β-, or γ- cyclodextrins. Usually, however the composition according to the invention will comprise only one of the a-, β-, or 7- cyclodextrins. The particular -, β-, or 7- cyclodextrin to be used with the particular cytotoxic compound to form the compositions according to the invention may be selected based on the known size of the molecule of the cytotoxic compound and the relative size of the cavity of the cyclodextrin compound. Generally if the molecule of the cytotoxic compound is relatively large, a cyclodextrin having a larger cavity is used to make the composition according to the invention. Furthermore, if the cytotoxic compound is administered with an excipient it may be desirable to use a cyclodextrin compound having a larger cavity in the composition according to the invention. The unmodified -, β-, or 7- cyclodextrins are less preferred in the compositions according to the invention because the unmodified forms tend to crystalize and are relatively less soluble in aqueous solutions. More preferred for the compositions according to the invention are the -, β-, and 7- cyclodextrins that are chemically modified or substituted. Chemical substitution at the 2,3 and 6 hydroxyl groups of the glucopyranose units of the cyclodextrin rings yields increases in solubility of the cyclodextrin compound. Most preferred cyclodextrins in the compositions according to the invention are amorphous cyclodextrin compounds. By amorphous cyclodextrin is meant non- crystalline mixtures of cyclodextrins wherein the mixture is prepared from -, β-, or 7- cyclodextrin. In general, the amorphous cyclodextrin is prepared by non-selective alkylation of the desired cyclodextrin species. Suitable alkylation agents for this purpose include but are not limited to propylene oxide, glycidol, iodoactamide, chloroacetate, and 2- diethylaminoethly chloride. Reactions are carried out to yield mixtures containing a plurality of components thereby preventing crystallization of the cyclodextrin. various alkylated cyclodextrins can be made and of course will vary, depending upon the starting species of cyclodextrin and the alkylating agent used. Among the amorphous cyclodextrins suitable for compositions according to the invention are hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotrosyl derivatives of /3-cyclodextrin, carboxyamidomethyl-/3-cyclodextrin, carboxymethyl-jS-cyclodextrin, hydroxypropyl-/3- cyclodextrin and diethylamino-/3-cyclodextrin . In the compositions according to the invention hydroxypropyl-/3-cyclodextrin is preferred although the a- or 7- analogs may also be suitable. The particular alkylated a-, β-, or 7- cyclodextrin to be used with the particular cytotoxic compound to form the compositions according to the invention will be selected based on the size of the molecule of the cytotoxic compound and the relative size of the cavity of the cyclodextrin compound. As with the unsubstituted cyclodextrins mentioned above, it may be advantageous to use alkylated cyclodextrin having a larger cavity when the composition according to the invention also includes an excipient. The use of a particular o;-, β-, or 7- cyclodextrin with a particular cytotoxic compound or cytotoxic compound and excipient in the compositions according to the invention may of course be optimized based on the effectiveness in reducing ulceration or irritation. Another significant factor in determining the anti-ulcerative and anti irritation effects of complexes of substituted cycldextrins and cytotoxic drugs is the degree of substitution of substituent groups in the cyclodextrin molecule, whether it is -, β-, or 7- cyclodextrin. By degree of substitution is meant the number of substituent molecules per molecule of cyclodextrin. In the compostion according to the invention a higher average degree of substitution of substuient groups in the cyclodextrin molecule is believed to be preferable. Such substitutent groups are exemplified by those mentioned in the paragraph above. A degree of substitution in the range of about 4 to about 10 for hydroxypropyl substituents may be effective with mitomycin-c. and doxorabicin. A degree of substitution in the range of about 5 to about 9 is preferred and is expected to be anti-ulcertaion effective for compositions including both water soluble anti-neoplastic agents such as those mentioned herein above and water insoluble antineoplastic agents such as taxol. As mentioned above, the compositions of matter of the invention comprise a cytotoxic compound and cyclodextrin. The relative amounts of cytotoxic compound and cyclodextrin will vary depending upon the relative toxicity of the compound and the effect of the cyclodextrin on the compound. In general, the ratio of the weight of cytotoxic compound to the weight of cyclodextrin compound will be in a range between 1 :20 and 1 :5000. Within this range, the ulcerative effects of many cytotoxic compounds will be significantly reduced when the ratio of the weight of cytotoxic compound to the weight of cyclodextrin compound is in a range between 1:50 and 1:2000. A weight to weight ratio in a range of 1:50 to 1:2000 and more preferably in a range of 1:50 to 1:800 of cytotoxic chemotherapeutic compound to cyclodextrin are believed to be effective for a number of vesicant anti-cancer chemotherapeutics. For example Mitomycin in a ratio of between 1:100 to 1:300 (drug to cyclodextrin) significantly reduces the extent of ulceration due to intradermally deposited mitomycin C. When mitomycin C in a weigh to weight ratio with β- hydroxypropyl cyclodextrin of 1 : 160 was injected intradermally in a mammalian subject the lesion resulting from the injection was about one third the size of the lesion cause by intradermal injection of the same amount of mitomycin C without the cyclodextrin compound. Furthermore when mitomycin-C together with the excipient mannitol in a weight to weight ratio with β- hydroxypropyl cyclodextrin of 1 : 400 (mitomycin: β- hydroxypropyl cyclodextrin) was injected intradermally in a mammalian subject, the lesion resulting from the injection was eliminated entirely in 80% of the test subjects, and in the remaining test subjects the lesion was about one tenth the size of the lesion cause by intradermal injection of the same amount of mitomycin C and mannitol without the cyclodextrin compound. The compositions of matter according to the invention may by supplied as a powder comprising the active pharmaceutical compound and cyclodextrin compound. If the composition is to be administered parenterally, for example iv, the composition of matter will be rendered sterile prior to such administration. Any of the several known means for rendering such pharmaceutical preparations sterile may be used so long as the active pharmaceutical compound is not inactivated. If the active pharmaceutical compound is heat stable, the composition of matter according to the invention may be heat sterilized. If the cytotoxic compound is not heat stable but is not photodegraded the composition may be sterilized by exposure to ultraviolet light. Alternatively, the composition of matter if in a powder form may be gas sterilized using for example ethylene oxide gas. In another alternative, the composition of matter according to the invention may be filter sterilized using a 2 micron filter. If the composition of matter is a aqueous liquid, it may be filled in a sterile container and supplied as a sterile liquid ready for further dilution or injection neat. Alternatively such sterile liquids may be freeze dried or lyophilized in a sterile container and capped. In general the compositions of matter according to the invention will be made by dissolving the cyclodextrin in water and adding the active compound to the aqueous cyclodextrin solution. Excipients, if any are desired may be added with or subsequent to adding the active compound. The resulting solution may be sterilized using any of the known methods appropriate to preserving the active compound. Alternatively, the components may be sterilized by any of the known methods appropriate to preserving the active compound prior to mixing in water an may be mixed using sterile equipment and technique. The solution may be lyophilized in sterile containers and capped. Prior to use the lyophilized composition of matter may be reconstituted using sterile water for injection. It will be understood that the compositions of matter according to the invention provide novel methods of controlling and reducing the incidence of ulceration associated with extravasation and irritation associated with intravenous administration of many pharmaceutical compounds. The compositions of matter according to the invention provide a method for reducing the likelihood of ulceration in subjects in need of parenteral treatment with compounds that if extravasated have the potential for causing ulceration, by administering to such subjects a preparation comprising at least one compound that if extravasated has the potential for causing ulceration and an anti- ulceration-effective amount of cyclodextrin or amorphous cyclodextrin. Furthermore, the compositions according to the invention provide a method for reducing the likelihood of irritation in subjects in need of parenteral treatment with compounds that when administered parenterally, particularly intravenously, have the potential for causing irritation, by administering to such subject a preparation comprising at least one compound that has the potential for causing irritation and an anti-irritation-effective amount of cyclodextrin or amorphous cyclodextrin. It will be understood that the present invention provides both compositions of matter and methods for the substantial reduction in injuries caused as a result of extravasation. While it is heretofore known that compositions of amorphous cyclodextrin and compounds that are not soluble in water because they are lipophilic have the property of reducing precipitation of compounds at or near the injection site, the heretofore known compositions and methods fail to make any observation on the effect of extravasated compounds , or the amounts of amorphous cyclodextrin needed to prevent the ulcerative effects of such extravasated compounds. Accordingly, the present invention is directed to compositions comprising anti ulceration-effective amounts of amorphous cyclodextrin and compounds that otherwise cause ulceration when extravasated. Such compounds may be soluble in aqueous solution or alternatively may be lipophilic and as a result tend to precipitate in aqueous solutions. Since amorphous cyclodextrins are taught in the art to solubilize compounds that are not soluble in water, it is surprising, and heretofore unobserved and unreported that compositions of matter comprising amorphous cyclodextrin and such insoluble compounds, which have been rendered soluble by complexation with cyclodextrin do not lead to ulceration when extravasated. This observation is especially surprising because water soluble cytotoxic compounds frequently cause ulceration when extravasated, and it would be expected that lipophilic cytotoxic compounds rendered soluble by complexation with cyclodextrin would similarly remain cytotoxic. Even more unexpected is the effect of forming complexes with cyclodextrin compounds on ulceration associated with extravasation using cytotoxic compounds that are soluble in aqueous solution and which are not expected to precipitate at or near the site of injection. Indeed, the literature on extravasation toxicity indicates that the problem of toxicity associated with extravasation of water soluble compounds is exacerbated by the solubility of these compounds. Such water soluble toxic compounds rather than precipitating appear to spread throughout the limb when extravasated. It is thus unexpected that the ulcerative toxicity of such compounds would be curtailed by complexation with a cyclodextrin compound or that complexation of such compounds that are soluble in aqueous solution with a cyclodextrin compound would occur at all. The invention will be better understood from the following examples which are intended to be merely illustrative of the invention and are not intended to be limiting. Example I Effects of Hydroxyproplycyclodextrin (HPCD) on Mitomycin-c Solubility Purified mitomycin C was divided into aliquot ranging from 0 to 10 mg and were place in pre- weighed 12 x 75 mm glass tubes. To each tube was added 1 ml of double distilled water, 20 % HPCD ( weight /volume (w/v) in double distilled water) or 40% HPCD w/v. HPCD had a degree of substitution of 7. Each tube was vortexed for 1 minute and allowed to stand at room temperature for 1 hour at which time they were revortexed for 1 minute. Tubes were then centrifuged for 4 minutes in a Triac centrifuge to concentrate the undissolved mitomycin-c in the bottom of the tube. The dissolved mitomycin, along with the diluent was decanted. The tubes containing the undissolved mitomycin-c were dried at 80 °C and reweighed to determine the weight of insoluble mitomycin-c. The results are shown in Table I. Table I % HP3CD dose mitomvcin-c (mε) mg insoluble % solubilitv (H 2 O) 0 0 - 1 0 100 2.5 0 100 5 2.7 46 10 6.0 40 20% 0 0 1 0 100 2.5 0 100 5 0 100 10 4.7 53 % HP/3CD dose mitomvcin-c toε) mg insoluble % solubilitv 40% 0 0 1 0 100 2.5 0 100 5 0 100 10 1.1 89 In water, mitomycin-c was completely soluble up to a concentration of 2.5 mg/ml, but solubility was limited to 46 % and 40 % at the 5 and 10 mg/ml concentrations, respectively. Hence in water the limits of solubility of mitomycin-c appeared to be about 2.5 mg/ml. Solubility of mitomycin-c was improved in HPCD. In 20% HPCD mitomycin-c was completely soluble at 5 mg/ml and 50% soluble at 10 mg/ml, indicating that the solubility limits in 20 % HPCD was about 5 mg/ml. In 40 % HPC, mitomycin- C was completely soluble through 5 mg/ml. These data indicate that 40% HPCD increased mitomycin-c solubility by 3- to 4-fold. Example II Effects of HPCD on Mitomycin-c Extravasation Toxicity Based upon the solubility study of Example I and a preliminary animal evaluation to optimize lesion size, 1.25 mg mitomycin-c in 0.5 ml of solvent (water or 40% HPCD) was used. Eighteen rats were divided into 3 groups. These groups of 6 rats each received the following injections at separate sites on the back: Group 1: Saline (0.5 ml) then saline (0.5 ml) Saline (0.5 ml) then 40% HPCD (0.5 ml) 40% HPCD (0.5 ml) Group 2: Mitomycin-c in saline (0.5ml) Mitomycin-c in 40% HPCD(0.5ml) Group 3: Mitomycin-c in saline (0.5ml) then saline (0.5 ml) Mitomycin-c in saline (0.5ml) then 40% HPCD (0.5 ml) Group 1 rats represent three different control injections.; Group 2 rats test mitomycin-c diluted in saline versus mitomycin-c in 40% HPCD; and Group 3 rats test the effects of subsequent saline or HPCD injection on mitomycin-c toxicity. HPCD had a degree of substitution of 7. All injections were made into the skin and the accuracy of the intradermal injection was verified by local blanching of the skin at the time of the injection. For Group 1 and 2, when sequential injections were made, the injection needle was left in place following the first injection and the second injection immediately followed the first . This insured that the second injection was delivered to the same intradermal site as the first. The results are shown in Table II.

Saline injection had no adverse effects when given intradermally. HPCD injections cause a small lesion whether it was administered after a saline injection ( sal ne + 40 % HPCD= 20% HPCD at the injection site) or alone 40% HPCD in 0.5ml.) The lesion produced by HPCD appeared to be concentration dependent and peaked at 4 days post injection. As the 20% HPCD lesion was small (3.5 mm) this dose of HPCD would appear to be optimal for the injections.. However as all injections were done on the same day and in as much as 40% HPCD was chosen, the following data should be viewed with respect to the contribution of HPCD to the lesion size. Mitomycin-c diluted in saline caused a 0.95 cm lesion by day 1 which increased in size to 1.45 cm by day 6 post injection. By contrast when mitomycin-c was diluted in 40% HPCD, lesion size was reduced by 2/3 each at each sampling time. The mitomycin-c-HPCD lesion was significantly smaller and it appears that mitomycin -C in HPCD can prevent greater than 50% the measurable extent of ulceration associated with extravasation of the chemotherapeutic agent. Administration of mitomycin-c followed by HPCD appeared to have little beneficial effect on the size of lesions. This may be because (i) mitomycin-c rapidly interacts with tissue in a manner which cannot be reversed by HPCD or (II) complexation of mitomycin-c and HPCD does not occur effectively in vivo. This latter possiblity is indicated by the observation that during the intradermal injection, mitomycin-c ( a blue color) was pushed to the periphery of the injection site by the subsequent HPCD injection. The high viscosity of the HPCD displaced the drug, rather than mixed with the mitomycin-c at the injection site. The subsequent injection of 40% HPCD was ineffective in preventing extravasation toxicity. As a result it is clear that prepartation of mitomycin-c in HPCD is superior to attempts to mitigate ulceration caused by extravasated mitomycin-C. Example III Effects of HPCD on Mitomycin with Mannitol as Excipient -Extravasation Toxicity Vials of mitomycin containing 10 mg of mannitol per mg mitomycin-c (Bristol Myers Oncology Division of Bristol Myers Squibb Company [herein after referred to as MM, 1 Unit (U) MM = 1 mg mitomycin C and 10 mg mannitol]) were diluted to 1 mg mitomycin-c /ml H 2 O or 40 % HPCD. HPCD had a degree of substitution of 7. Vials were vortexed for 1 min, allowed to sit at room temperature for 1 hr and were vortexed again for 1 min. Five rats received an injection of 1 U MM/ ml saline as described above on one side and 1 UMM/ml 40% HPCD on the opposite side of the back. The results are reported in Table III.

Example IN Preservation of Mytomycin-C Toxicity The observations concerning toxicity as shown by change in body weight is in Study 2 and 3 is shown in Table IV.

These studies were terminated at 4 to 6 days post administration respectively as the dose of mitomycin needed to produce consistent and readily measurable lesions was very toxic to the rats. In Study 2 and 3, , Mitomycin-c treated rats lost about 25% of their initial body weight over 6 and 4 days post administration respectively. All animals receiving MM had sever diarrhea, were cold to the touch and were inactive Five of 12 mitomycin-treated study 2 rats died between days 4 and 6. All study 3 rats died by day 6. The small initial size of the study 3 rats may have contributed to the increased mortality. In no case did the systemic toxicity influence the formation skin lesion which were apparent by day 1 prior to occurrence of any diarrhea or decrease in weight gain. Systemic toxicity of the HPCD-mitomycin and HPCD-MM formulations was not reduced as compared to equivalent doses of mitomycin-C in water indicating that the toxicity required for effectiveness of mitomycin-c for use as an anticancer agent is not impaired by formation of the mitomycin-c-cyclodextrin complex or the mitomycin-c- cyclodextrin complex with excipient. Example V Doxorubicin HPCD Formulation Animals were injected with one of 5 solutions prepared as follows: Solution A consisted of 2.5 mg mannitol and 0.2 gm HPCD in 0.5 ml of saline. The mannitol dose is equal to that used in the doxorabacin commercial vehicle and the HPCD was 20% weight/volume (of saline). Solution B consisted of 2 mg doxorabacin and 2.5 mg mannitol/0.5 ml saline (hereafter referred to as doxorabacin in commercial vehicle). Solution C consisted of 2 mg doxorabacin, 2.5 mg mannitol and 0.2 gm HPCD in 0.5 ml saline hereafter referred to as doxorabacin in 20% HPCD). All HPCD had a degree of substitution of 7. Animal Use Male Charles Rivers CD (Sprague-Dawley) rats were anesthetized with metaphane (inhalant), marked for continuous identification and weighed. The hair on the mid-section of their back was shaved, the skin was thoroughly scrubbed with 70% ethanol and one of the aforementioned 5 solutions was administered by a single intradermal injection using a sterile 1 cc tuberculin syringe and a 27 gauge needle. Eight rats were treated per group. At 1, 3, 6, 13 and 20 days after the injection, rats were weighed, the size of the lesion was measured, the lesion was described and the general health of the rats was assessed and recorded. Lesion diameter was determined by measuring the greatest and least extent of the lesion and the average of the 2 measurements was reported. The measurement of lesions and inspection of animals was done without anesthesia. Results Body Weight The effects of intradermal injection of 20% HPCD and doxorabacin on body weight in adult male rats is depicted in Table 1. As we had previously reported, 20% HPCD has no effect on body weight as animals continued to gain weight throughout the sampling period. This is the expected weight response of young adult male rats. Treatment with doxorabacin in commercial vihicle (CV) had no adverse effect on body weight and treatment with doxorabacin in 20% HPCD only modestly reduced the rate of weight gain in rats. Indeed, this latter group of rats appeared to gain weight normally through the 1st post-injection week, then showed a slight decline in the rate of weight gain thereafter. All animals treated intradermally with doxorabacin appeared to be healthy and showed no adverse effects of the drag, other than the skin lesions, as intended. Lesion Size The effects of intradermal administration of doxorabacin on lesion size is depicted in Table 3. Intradermal injection of 0.5 ml of 20% HPCD caused no effect in 7 of 8 rats tested. The remaining one animal developed a small lesion (0.3 cm diameter) which was observed on day 3 and 6 and which had healed completely by day 13 post injection. This observation is consistant with previous observations. Doxorabacin in CV caused necrotic lesions of the skin in all 8 rats tested which persisted throughout the observation period. The lesions were evident by day 3, peaked in diameter at 0.73 ±0.04 cm on day 6 and were slightly reduced in size on day 13 and 20. Doxorubicin in 20% HPCD showed a different response. On day 3 only 4 of 8 rats had shown lesions, on days 6 and 13, 6 of 8 rats exhibited lesions and on day 20, 4 of 8 rats had lesions. In the Doxorabacin in 20% HPCD group, 4 of the rats showed lesions that persisted through day 20. Two rats failed to exhibit lesions at any sampling time. The final two rats, showed small lesions which first appeared by day 6, were present at day 13 and were completely healed by day 20. As a result, the diameter of the lesions produced were lower in the Doxorubicin-20% HPCD group than in the Doxorabicin-in CV group at each sampling time from day 3 to day 20. Description of Lesions For 7 of 8 rats injected with the vehicle, no lesion formed and there was no evidence of an injection effect by the 1st day after injection. In the single animal which showed a lesion, a small, brown (necrotic) area was evident by day 3, but had healed by day 13. For animals injected with doxorabacin in c.v., rats exhibited at the time of the injection and at 1 day post-injection, a red colored area of the skin indicative of the deposition of the red colored doxorabacin. On the 1st post-injection day, the center of this reddened area was brown (necrotic) in 4 of 8 rats, but it was too small to measure. By day 3 post-injection, lesions had formed in all 8 rats and scabs had covered the damaged tissue. These scabs were well defined, persisted through the remainder of the study and were used to measure the extent of the lesions. Animals injected intradermally with doxorabacin formulated in 20% HPCD showed 2 subgroups. The first subgroup of 4 rats showed lesions which were similar in their progression and size to those seen in the doxorubacin-c.v. group. That is, these animals showed red coloration at the injection site on day one and exhibited lesions with scabs by day 3 postinjection. By contrast, the second subgroup, which consisted of 2 animals which did not develop lesion and 2 animals which developed small, rapidly healing lesions, showed a different response to injection. First at one day after injection, the red coloration (drug) at the injection site was either non-existent or very faint. Thereafter, 2 animals failed to develop skin lesions, and 2 animals exhibited lesions which were small in size and rapidly healed. An example of this latter, small lesion subgroup is animal #13, which on day 4 of the day of the photograph, a red area was noted, but no lesion waspresent. This rat would develop a small lesion which was present on day 6 smaller on day 13 and completely healed by day 20. Brief Interpretation of Data From the data presented here and from my previous report, it appears that HPCD may be effective in reducing skin lesion size and the incidence of skin lesions by dispersing the complexed drug from the injection site. In our previous study, we noted that lesions which form following intradermal injection were more diffuse in nature when mitomycin was formulated in HPCD versus commercial vehicle. In the present study, we found two evidences for the same phenomena. First, at one day following doxorabacin-HPCD injections, one-half of the injected rats failed to exhibit or showed only faint evidence of the red color associated with drag deposition. These animals were either lesion free or subsequently formed only small lesions.

Solution A consisted of 20% (w/v) of HPCD and represented the vehicle for injection. Solution B consisted of a 50% ethanol solution of Taxol (1.25 mg/0.5 ml; hereafter referred to as Taxol in CV). Solution C consisted of 20% HPCD in ethanol/water (1/1, w/v; hereafter referred to as Taxol in HPCD). HPCD had a degree of subsitution of 7. Male Charles Rivers CD rat eight rats per group were prepared and injected as in Example V with a single intradermal injection of the indicated solution using a sterile 1 cc tuberculin syringe and a 27 g needle. At 1, 3, and 7 days after the injection, rats were weighed, the size of the lesion was determined, the lesions were described and the general health of the rats was assessed and recorded. Body Weight and General Health The effects of Taxol administration on body weight is depicted in Table VI. All animals showed an increase in body weight following the injection. The range of increase did not differ significantly between groups. These data indicate that the drags were well tolerated by the animals regardless of the vehicle used for the injection. Additionally, the animals appeared to be in good health and no abnormalities, other than the induced lesions, were observed. Lesion Size The effects of Taxol injection intradermally on lesiforming lesions of the skin are shown in Table 2. The 20% HPCD vehicle itself, caused no lesions. Taxol in CV caused lesions of 1.52 ±0.4 cm diameter by day 1, in all 8 rats injected, and the size of the lesions remained the same through the remaining sampling periods. When formulated in HPCD, Taxol caused no lesions by day 1, and on days 3 and 7, six of 8 injected rats showed lesions. The lesion size was reduced to 1/3 of that obselved in Taxol-CV injected rats on both day 3 and 7. Description of Lesions The lesions produced by Taxol in CV were necrotic lesions which destroyed the skin at the injection site in a manner which clearly related to the deposition of drug at the injection site. On day one, the lesions were characterized by a large white center with a red halo arond it. The lesions were very consistent in diameter as reflected in the small standard error in the data for the Taxol-HPCD group (see Table ). By day three, lesions were maximal in size, were fully necrotic and had scabbed. Little change occurred through day 7. When formulated in HPCD, Taxol failed to cause lesions on day 1 ; at this time, 5 of 8 rats showed evidence of redness at the site of deposition of the drug. On day 3, the lesions observed were similar to these seen in the Taxol-CV group, but were smaller in size by 2/3. On day 7 all lesions were well healed and again at this time were smaller in size than those seen in the Taxol-CV group. The results of these studies indicate that HPCD exerts a protective effect on skin when Taxol is deposited into an intradermal site. Indeed, this effect is substantial, resulting in a 2/3 reduction in lesion size.
